Y-STRs in forensic medicine: DNA analysis in semen samples of azoospermic individuals

ABSTRACT: The incidence of rape has increased, especially in metropolitan areas, such as the city of São Paulo. In Brazil, studies about it have shown that the majority of this type of crime is committed by the relatives and persons close to the victim. This has made the crime more difficult to be denounced, as only 10% of the cases are reported to competent police authorities. Usually, cytological exams are carried out in sex crime investigations. The difficulty in showing the presence of spermatozoa is frequent, but it does not exclude the presence of male DNA. The absence of spermatozoa in material collected from rape victims can be due to several factors, including the fact that the agressor suffers from azoospermia. This condition can be the result of a successful vasectomy. As the majority of DNA in the ejaculation sample is from spermatozoa, there is much less DNA to be analyzed. This study presents the application of Y‐STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) in DNA analysis of sperm samples from 105 vasectomized men. The study demonstrated a great variation in DNA concentration. DNA extraction and amplification was possible in all sperm samples even in the absence of spermatozoa. The same profile was observed, for each individual, from DNA extracted from blood, pre‐ and postvasectomy semen samples. The use of markers specific for Y chromosome in sex crime cases, especially in the absence of spermatozoa, is very important, mainly because in most situations there is a small quantity of the agressor's DNA in the medium and a large quantity of the victim's DNA.     

Sex offender residence restriction laws: Parental perceptions and public policy

Despite a steady decline in sex crime over the past twenty years, new laws, such as residence restrictions, targeting such crime have proliferated. Some scholars have argued that public concern about sexual offending against young children has served as a catalyst for the emergence of these laws. Few studies, however, have empirically tested this claim. To address this gap and to contribute to scholarship on public opinion about crime and justice, this research tests a central implication flowing from prior work—namely, the notion that people with children will be more likely to endorse increased restrictions on where sex offenders can live. Analyses of public opinion data from a 2006 poll of Florida residents suggest that parents are indeed significantly more likely to support such restrictions. Implications of the study for research and policy are discussed.     

Self-Reported Communication Variables and Dating Violence: Using Gottman’s Marital Communication Conceptualization

Communication behaviors, while extensively studied within the marital field, have received only peripheral attention in violent dating relationships. The purpose of this research was to better establish empirical continuity between the marital and dating literatures by exploring communication variables that have been identified in marital relationships broadly and their self-reported manifestation in violent dating relationships. Using Gottman’s (1999) marital communication conceptualization, individuals were assessed on adaptive and maladaptive communication variables and relationship aggression. Results suggested that negative communication behaviors were associated with, and predicted, aggression in participants’ dating relationships, consistent with findings from the marital literature. However, repair attempts, generally considered an adaptive communication behavior, predicted aggression victimization. Implications and how these data fit within the context of recent research on positive marital communication behaviors are explored.     

Court Sentencing Patterns for Environmental Crimes: Is There a “Green” Gap in Punishment?

Objectives

This study examines sentencing patterns for environmental crimes and tests the assumption that “green” offenders receive more lenient treatment from criminal courts than non-environmental offenders.

Methods

We present two sets of analyses. First, we present an empirical portrait of environmental felony offenses convicted in a single state (Florida) over a fifteen-year period and the resulting criminal sanctions. Second, we use a precision matching analysis to assess whether environmental offenders receive more lenient treatment when compared to non-environmental offenders with the same characteristics and offense severity scores.

Results

Findings indicate that an overall small percentage of felony convictions in state courts stem from environmental crimes. We also find that punishments for environmental crimes are more lenient than sanctions assigned to comparable non-environmental offenses when the environmental crime is ecological, but that punishments are sometimes harsher when the environmental crime involves animals.

Conclusions

The findings provide general support for the argument that courts and other formal institutions of social control treat environmental crimes more leniently than non-environmental crimes. This paper also raises important questions about citizen and state actors’ perceptions of crimes against the environment and, more generally, about the ways in which theories of court sentencing behaviors apply to environmental crime sanctioning decisions.

     

Judging the Judiciary: Understanding Public Confidence in Latin American Courts

Although there is a substantial literature examining public confidence in the judiciary in developed nations, scholars have paid scant attention to analyzing judicial confidence in developing countries. Building on extant work regarding developed nations and introducing original hypotheses in the context of developing nations, this research explains influences on public confidence in Latin American judiciaries by developing a theory that focuses on the potential influences of institutional quality, experiences, and individual attitudes. The hypotheses are empirically tested with the rich individual‐level data compiled by the Latin American Public Opinion Project 2006 survey. The results indicate that a variety of factors influence public confidence in Latin American courts; the role of context explains points of consistency and divergence with research on developed nations.     

Developing a Tripartite Prevention Program for Impoverished Young Women Transitioning to Young Adulthood: Addressing Substance Use,HIV Risk,and Victimization by Intimate Partners

Little is known about the transition to adulthood for adolescent females and young women who are impoverished and homeless. Co-occurrence of drug use and abuse, HIV risk, and victimization is notable among homeless women, highlighting the need for comprehensive interventions. Unfortunately, evidence-based prevention approaches addressing these inter-related problems among impoverished women transitioning into adulthood are lacking. To address this gap, we designed an innovative prevention program by utilizing open- and closed-ended interview data from impoverished women (n = 20), focus groups with community experts and providers (2 groups; n = 9), and a theoretical framework to direct the research. Information provided by our focus groups and interviews with women supported our theoretical framework and highlighted the importance of addressing normative information, providing skills training, and utilizing a non-confrontational approach when discussing these sensitive issues.     

The PIRA,D-Company,and the Crime-Terror Nexus

This article compares and contrasts the Provisional Irish Republican Army (PIRA) and D-Company, two seemingly dissimilar organisations that nonetheless share some striking commonalities, especially in regards to the use of tactics that contradict their declared ideology in pursuit of a larger goal. First, the growing relationship between organised criminal syndicates and terror groups is discussed and Makarenko's well-known “Crime-Terror Continuum” introduced. Following this, a historical overview and an analysis of the organisational structure of the PIRA is provided and organisational models proposed. Further, the founding and development of D-Company is addressed in addition to the syndicate's intricate involvement in the 1993 Bombay Blasts. Similarly, organisational models are offered and conclusions drawn. This work then moves to a comparative analysis of the organisational and operating structure of the PIRA and D-Company and finishes with a brief conclusion. This article argues that although criminal syndicates and militant groups may have different organisation structures, the line that distinguishes their activities has begun to blur and the space between Makarenko's graduated levels is becoming smaller and less discernible, thus rendering her model obsolete.
